Обсуждение: Old parser feature

Hey, check it out:

postgres=> select case_tbl.*; i|    f
---+------3| 10.1-6| 20.2-9|-30.3
-12|
(4 rows)

Notes in the parser say this was allowed with POSTQUEL, so was retained
when implementing SQL...

Yes, nice feature.  QUEL allowed:
retrieve (case_tbl.all)

In fact, QUEL never had a FROM clause in the SQL sense.
